A post on HHN's Facebook page said it would be an all-new, original house.

"The train convoy has derailed and the bloodthirsty maniacs are loose," the post says. "Escaping them this time will be a hard feat ... the 'Dogs of War' return to HHN23 in this sequel house."

On Wednesday, Universal announced a house called Afterlife: Death's Vengeance. And Early Tuesday morning, a house called Urban Legends: La Llorona was revealed.

A final reveal is expected Friday.

The theme park previously announced houses themed to the horror films "The Cabin in the Woods" and "Evil Dead," plus the return of "The Walking Dead" house based on the AMC television series. In addition, Universal has said that its scare zones will be entirely devoted to scenes from "The Walking Dead."

The 23rd edition of Halloween Horror Nights begins Sept. 20 and runs for 27 select nights through Nov. 2. It is an after-hours event that requires a separate ticket from regular theme-park admission. For tickets or more information, go to HalloweenHorrorNights.com/Orlando.
